Elevator noise is a common noise in residential areas, and the noise level during elevator operation is around decibels. Seriously exceeding national standards and causing adverse effects on the daily lives of surrounding residents. The elevator sound insulation treatment plan can effectively solve the problem of elevator noise. After treatment, the noise level is below 45 decibels during the day and not greater than 35 decibels at night. Comply with national noise emission standards and achieve satisfactory results for residents.
1、 Background of Elevator Soundproofing Treatment Project
During the normal operation of an elevator in a residential area in Hangzhou, it caused indoor noise of 50 decibels among surrounding residents. Exceeding relevant national regulations and causing serious impacts on residents' daily lives.
2、 Elevator sound insulation treatment plan
1. Noise source
The mechanical noise caused by the traction machine in the elevator machine room during operation is mostly low to medium frequency noise. And track friction noise and cabinet vibration noise are both sources of noise.
2. Shock absorber platform
Installing a shock-absorbing platform under the elevator host not only blocks the propagation structure of low-frequency noise, but also reduces the transmission rate of noise, as well as the vibration and brake noise of the elevator host, thereby solving the problem of low-frequency noise caused by elevator vibration.
3. Elastic bracket
Use elastic brackets to change solid connections and reduce noise and noise propagation caused by track friction.
4. Inorganic fiber spraying
Using inorganic fiber spraying in the shaft can not only improve the sound insulation effect of the shaft, but also reduce the overall noise generated by the elevator shaft.
3、 Elevator sound insulation treatment effect
After the elevator sound insulation treatment plan, the indoor noise level of residents was measured on site to be 26 decibels. Comply with relevant regulations such as the "Social Living Environment Noise Emission Standards".
The elevator sound insulation treatment plan mainly focuses on vibration reduction, and the noise reduction methods vary according to the actual environment on site. The most common elevator noise is still reduced by equipment, which can effectively solve the elevator noise problem.
